单选题Sky-high gasoline prices aren"t just raising the cost of Eugene Marino"s 120-mile (193-kilometer) round-trip to his job in the Washington area. They"re reducing his wealth, too. House prices in his rural subdivision beyond the Blue Ridge Mountains in Charles Town, West Virginia, have plunged as commuting expenses have soared. A four-bedroom home down the street from his is listed for $239,000, after selling new for $360,000 five years ago. Homeowners in the exurbs aren"t the only ones whose assets have taken a hit because of the surge in energy costs. Companies such as General Motors Corp. are writing off billions of dollars in plants and equipment that are no longer viable in an age of dearer oil. The destruction of wealth and capital will weigh on U.S. growth for years to come. "Our whole economy reflects the relative costs of energy: the cars we drive, the houses we occupy, the kinds of factories we have and the equipment in them," says Dana Johnson, chief economist at Comerica Bank in Dallas. "I"m expecting relatively large changes in all of these things." The loss of wealth could be a double whammy for the U.S. economy. In the short run, it depresses demand as homeowners save more and spend less, and companies fire workers. Longer run, it curbs productivity growth, as firms shift their focus from increasing worker efficiency to reducing energy costs. "At $4 per gallon gas, $125 per barrel oil and $10 per million Btu natural gas, a lot of activity becomes uneconomical," says Mark Zandi, chief economist at Moody"s Economy.com in West Chester, Pennsylvania. The lifestyle of the exurban commuter may be one casualty. Emerging suburbs and exurbs—commuter towns that lie beyond cities and their traditional suburbs—grew about 15 percent from 2000 to 2006, nearly three times as fast as the U.S. population, as Americans moved further out in search of more affordable houses or the bigger ones that are sometimes derided as McMansions. "It was drive until you qualify for a mortgage," says Robert Lang, director of the Metropolitan Institute at Virginia Tech in Alexandria, Virginia. "You can"t do that anymore. Your cost of transportation will spike too much."

单选题

单选题What we know of prenatal development makes all this attempt made by a mother to mold the character of her unborn child by studying poetry, art, or mathematics during pregnancy seem utterly impossible. How could such extremely complex influences pass from the mother to the child? There is no connection between their nervous systems. Even the blood vessels of mother and child do not join directly. An emotional shock to the mother will affect her child, because it changes the activity of her glands and so the chemistry of her blood. Any chemical change in the mother's blood will affect the child for better or worse. But we can not see how a looking for mathematics or poetic genius can be dissolved in blood and produce a similar liking or genius in the child. In our discussion of instincts we saw that there was reason to believe that whatever we inherit must be of some very simple sort rather than any complicated or very definite kind of behavior. It is certain that no one inherits a knowledge of mathematics. It may be, however, that children inherit more or less of a rather general ability that we may call intelligence. If very intelligent children become deeply interested in mathematics, they will probably make a success of that study. As for musical ability, it may be that what is inherited is an especially sensitive ear, a peculiar structure of the hands or the vocal organs connections between nerves and muscles that make it comparatively easy to learn the movements a musician must execute, and particularly vigorous emotions. If these factors are all organized around music, the child may become a musician. The same factors, in other circumstance might be organized about some other center of interest. The rich emotional equipment might find expression in poetry. The capable fingers might develop skill in surgery. It is not the knowledge of music that is inherited, then nor even the love of it, but a certain bodily structure that makes it comparatively easy to acquire musical knowledge and skill. Whether that ability shall be directed toward music or some other undertaking may be decided entirely by forces in the environment in which a child grows up.

单选题Until recently, women in advertisements wore one of three things—an apron, a glamorous dress or a frown. Although that is now changing, many women still feel angry enough to deface offending advertisements with stickers protesting, "This ad degrades women." Why does this sort of advertising exist? How can advertisers and ad agencies produce, sometimes after months of research, advertising that offends the consumer? The Advertising Standards Authority (the body which deals with complaints about print media) is carrying out research into how women feel about the way they are portrayed in advertisements. Its conclusions are likely to be what the advertising industry already knows: although women are often irritated by the way they are seen in ads, few feel strongly enough to complain. Women are not the only victims of poor and boring stereotypes--in many TV commercials men are seen either as useless, childish fools who are unable to perform the simplest household tasks, or as inconsiderate boors, permanently on the lookout for an escape to the pub. But it is women who seem to bear the brunt of the industry"s apparent inability to put people into an authentic present-day context. Yet according to Emma Bennett, executive creative director of a London advertising agency, women are not infuriated by stereotypes and sexist advertising. "It tends to wash over them; they are not militant or angry-they just find it annoying or tiresome. They reluctantly accept outdated stereotypes, but heave a sigh of relief when an advertisement really gets it right." She says that it is not advertising"s use of the housewife role that bothers women, but the way in which it is handled. "Researchers have often asked the wrong questions. The most important thing is the advertisement"s tone of voice. Women hate being patronized, flattered or given desperately down-to-earth common sense advice." In the end, the responsibility for good advertising must be shared between the advertiser, the advertising agency and the consumer. Advertising does not set trends but it reflects them. It is up to the consumer to tell advertisers where they fail, and until people on the receiving end take the business seriously and make their feelings known, the process of change will remain laboriously slow.

单选题 "In every known human society the male's needs for achievement can be recognized... In a great number if human societies men's sureness of their sex role is tied up with their right, or ability, to practice some activity that women are not allowed to practice. Their maleness in fact has to be underwritten by preventing women from entering some field or performing some feat." This is the conclusion of the anthropologist Margaret Mead about the way in which the roles of men and women in society should be distinguished. If talk and print are considered it would seem that the formal emancipation of women is far from complete. There is a flow of publications about the continuing domestic bondage of women and about the complicated system of defences which men have thrown up around their hitherto accepted advantages, taking sometimes the obvious form of exclusion form types of occupation and sociable groupings; and sometimes the more subtle form of automatic doubt of the seriousness of women's pretensions to the level of intellect and resolution that men, it is supposed, bring to the business of running the world. There are a good many objective pieces of evidence for the erosion of men's status. In the first place, there is the widespread postwar phenomenon of the women Prime Minister, in India, Sri Lanka and Israel. Secondly, there is the very large increase in the number of women who work, especially married women and mothers of children. More diffusely there ate the increasingly numerous convergences between male and female behaviour: the approximation to identical styles in dress and coiffure, the sharing if domestic tasks, and the admission of women to all sorts of hitherto exclusively male leisure-time activities. Everyone carries round with him a fairly definite idea of the primitive or natural conditions of human life. It is acquired more by the study of humorous cartoons than of archaeology, but that does not matter since it is not significant as theory but only as an expression of inwardly felt expectations of people's sense of what is fundamentally proper in the differentiation between the roles of the two sexes. In this rudimentary natural society men go out to hunt and fish and to fight off the tribe next door while women keep the fire going. Amorous initiative is firmly reserved to the man, who sets about courtship with a club.
